To all 'whom it may concern:

Be it known that I, CHARLES E. BA'rI-inrcx, a citizen of the United States, residing at` Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements, in Mixer Feed Devices, of which the following is a specification.

My invention relates to a mixer feed device of the kind in which the material is elevated to a point Where it is discharged and delivered to a mixer for making concrete, mortar and the like.

The objects of my invention are, to provide a compact and efiicicnt automatic side loader for feeding mixers; tp avoid detaching the side loader from a carriage supportin a mixer and motor; to balance the side loa er mixer and motor or engine upon a carriage which can be moved to and stationed at any desired point for loading and mixing; to provide a hopper which can be swung outwardly and downwardly into recumbent position by shoveling, and in alternation therewith swung upwardly into an upright position and elevated so as to bring its discharge opening opening commumcating with the receptacle into which the contents of the hopper' is lo be unloaded or discharged; and to provide various other matters of construction andiar rangement serving to the attainment of an eiiicient and exceedingly useful device.

In the accompanying drawings: Figure i is a side elevation of a wheeled carriage or vehicle provided with a mixing machine and my improved feed device. Fig. 2 is an end l, the elevating hopperrelceptacle being elevated and in `position for charging ,the mixing receptacle. Fig. 3 is a like elevation showing the hopper or receptacle in its lowered receiving position. Fig. 4 is a section on a vertical central plane through a portion of the apparatus on a larger scale than in receding iigures, the section being princi a y through the mixing receptacle and 1 t re elevated hopper. Fig. 5 mainly shows'in elevation the mixing rece taclc and a portion of means for operating t e mixing receptacle and a hoist, the elevation being the result of `a section taken transversely through Fig. l on line x-z, and the view being on a larger scale than the View in Fig. 1. Fig. 6 is a side elevation on an enlarged scale showing operating devices for actuating the mixing receptacle, and a drum l) for the cable hoist.

A indicates awheeled carriage constructed with a suitable body 1 having front wheels 2 and rear wheels 3. 'lhc rotary mixing receptacle B issupported over the forward portion of the body, the rear portion of such ody being utilized as a support for an engine or motor C. of any suitable type and serves to drive the rotary mixing receptacle B, and also to operate a winding drum 'D when it is desired to revolve such drum in a direction to elevate a supply hopper E into position for discharging its contents into the rotary mixing receptacle, as hereinafter more particularly described.

The rotary engine shaft 4 is arranged longitudinally wlth relation to the carriage, and is supported at one side of a base su port 5 for the engine. ,This rotary engine s aft is provided with a driving pinion 6 (best shown in Fig. 1), which engages and operates a gear Wheel 7 arranged over the pinion. The ear 7 is secured upon one end portion of a s iort rotary shaft having its opposite end provided with a bevel gear 8, the shaft thus rovided with gears 7 and 8 being su porte( b any suitable bearing on a stan ard 9 su stantially midway of the length of the carriage body. The bevel gear or pinion 8 engages a ring gear 10 on the mixing receptacle, and by this simple connection between the engine and the mixing receptacle, the latter is rev olved continuously durin?r the operation of charging, mixing and discharging. The ro tary mixing receptacle is provided with an inlet ll (Fig. 4), and an outlet 12, and is supported to revolve about an axis with which said openings are concentric or substantially so. he mixing receptacle is mounted to thusy revolve upon a tiltin frame I`I`, said frame 'being suspended by liangers 13 from suitable bearings respcctivel on standard 9 and on a correspondin an `oppositely arranged standard 14, it eing o )served that the standard 14 is" upon ythe forward end portion of the carriage bod and that the mixin receptacle is hung to tilt about an axis whichg is longitudinal with relation to the length of the carriage body and in a vertical plane inidway or substantially midway of the width of the carriage body so as to maintain a suitable balance? The tilting frame F which supports the rotary mixing receptacle, is pro- The engine or motor l is vided at one end with a chute G, which is secured upon the tilting frame so as to move 'lhe mixing receptacle 1s arwith the latter` ranged above the body ot the vehicle and as the latter is mounted on wheels, it is desirable i to provide means for raising and lowering the l hopper, so .that during olieration, the hopper can be lowered and charged from whcelbarrows` on the ground level, and then raised so as to permit it to discharge into the mixing receptacle when the latter is in position for mixing.

rl`he hopper E is constructed with an outlet portion and side walls 16, which flare upwardly from its said outlet portion 15, the upper portion of the hopper being formed or provided with a partially covered upward extension 17, having a receiving opening 18 (Fig` 4), formed on an incline to a vertical central line through the hopper, or in other words, the sides 16 are extended upwardly to form the u ward extension 17, which is partially close( by the overhanging upper end 1f), therebyleaving between, the o lening 18,11aving two inclined side edges. lIVhen therefore the hopper thus shown in Fig. 2 has been lowered to the ground asin Fig. 3, its opening 18 will stand as an upwardly exposed doorway into which materials can he readily dumped from Wheelbarrows or thrown by shovels. lVhen the hopper is down as in Fig. 3, its een tral longitudinal line or axis which is vertical' in Fig. 4A is now substantially horizontal, it being also observed that when the hopper is in position for filling as in Fig. Il, the plate or end portion 19 which partially closes the outer larger' end of the hopper, is vertical or substantially so and permits a suitable quantity o' materials to be thrown into and rctained within the hopper. By forming the mouth or receiving opening 18 of Jthe hopper on a plane which is inclined to the axis ol' the hopper, the materials can be more readily dumped into the hopper when the latter is in its receiving position. 'lhc hopper is provided at its discharge end with a swinging valve device ll. This valve device which is best shown in Fig. 4, is constructed with a plate20 arranged for closing and opening thc outlet 21 of the discharge end portion 15 of the'hopper, and this valve plate 2l) is also provided with two oppositely,arranged side Y' plates-22 and 23, which are in the nature ol' flange plates along two longitudinal edge portions ot' the valve plaie 2U. 'lhe valve device ll is innig upon the hopperso that it can be swung outwardly to l'orin4 a temporary trough-like extension ol' the outlet portion 15 of the hopper, asin Fig. 4, and in alternation therewith swung in direction to bring the .yalve plate 2() in position to close outlet 2] of the hopper and perrnitils side plates 22 and 23 to embrace faipositesdes ol' the lower discharge portion 15 of the hopper. The valve device [l is operated by a lever 24 which is l pivoted at 25 upon a bracket 26 on the hoppor7 the short end of said level' being pivotal] attached to one` end ol a rod or bar 27, wliicli has its opposite end pivoted at 28 to an arm 2S) secured to the valve plate 20. 'l`he lever 24 can he operated to open the valve device l1 as in F ig. 4, and it can also be operated to close and lock the valve device as in Fig. 3, wherein the short arm of the level' and the rod 27 have been brought into alinement or on a dead center so as to temporarilyloek the valve device.

In order to permit the valve device to swin'g for purposes hcreinbefore mentioned, it is provi; ed upon each side with a plate or metal strap 3() (Fig. 3), which is rigidly secured to the valve device, said two lates 30 being provided at their outer en( with a transversely arranged iivot 31, which is attached to substantie leaves 32 (Fig. 1), each ng one leg supporting the pivot and having its remaining leg secured to the lower portion of'the hopper, as best illustrated in Fig. 1.

'lhe hopper is raised and lowered upon an inclined track I arranged at one side of the machine and'suitably supported by braces 33, 34, 35 and 36, arranged in any suitable mechanical way. The track I comprises two guide rails, each of said guide rails being in turn formed by two angle bars 37 and 38 arranged so that the s ace between the inner flanges of each pair o said angle barsflorms a longitudinal guide way for the wheels 39 of a truck K, it being understood that each wheel is flanged at one end and that its tread or bearing portion is of less diameter thap the space between the two flanges forrt'nng a. guide for tlie wheel, and that when the truck is moved up or down, thebearing portions of its wheels will roll upon the inner'sides or flanges 41 (Fig. 4), or upon the inner sides of the flanges 4() of the track as it may ha pen. 'lhe truck K is of simple construction eilig merely the two axles 42 and 43 connected by side plates or bars 44 and 'provided with the flanged wheels 39, illustrations of the truck being best afforded by Figs. 1 and 2. The axle 43 of the truck is permanently attached to the hopper at a point adj acont to the hopper outlet as in ig. 4, and to such end a heariri' f on the axle 43 is provided by a bar 45 (Fig. i) arranged transversely to the track and secured to what. may he termed the front side of the hopper. 'lhe lower truck axle 43 irovides a hinge connection between the lower portion of the hopper and the lower portion ol the truck, and permits the hopper to he swung about the axis of said truck axle 43. 'l`hc upper larger end portion of the hopper is provided at its front side with a catch device for engaging the truck when the hopper is swung into the position shown in Fig. 4, a simple arrangement being to provide the hopper with one or Inorevpreferly U-shaped hinge` iavi ably two-forwardly projecting catches or catch arms 46, each having a notch 47 arranged to en rage with the upper truck agile 42 when the opper is swung from its receiving. position into its discharging position.

As a means for raising and lowering the hopper together with the truck to which the hopper is attached, a cable .his applied to and extended from the rotary winding drum D up to and over' an elevated sheave 48 (Fig. l), thence to and over a suitable sheave in a sheave block 49 suspended from a cross-bar 50 at the upper end of the inclined track, thence downwardly to and under a sheave 51, which is connected with the hopper, and thence upwardly to the sheave block 49 to which its terminal is secured as in Fig. 1. The sheave 51 is suitably journaled upon a cross plate or bar 52, said bar 52 being `arrange transversely to the line of track, and being hirige-connectedl with the hopper by a pair of links 53 (Fig. 1), so that while thc sheave 51 can assume the position shown in Fig. 4, it can also be made to assume the position shown in Fig. 3, wherein the cross-bar .52 is temporaril against the hopper. After the hopper has een charged, it can be raised from the position shown in Fig. 3 into the position shown in Figs. l, 2 and 4, by operating the winding drum in a direction to wind thereon the cable L. 4The cable while thus operating will swing the hopper about the axis of the lower axle 43 of the truck until the catch 46 of the ho vper engages the upper truck axle 42, thereby bringing the longitudinal axis of the hopper into an upright position, and also bringing the hopper into position for discharge, it being observed, how-` ever, that at this time the discharge outlet of the hopper is closed by the valve device H. Further operation of thc cable L serves to draw the truck upwardly along the inclined track and this operation is continued until the now upright hopper reaches a position for dischargingr into the mixing receptacle, and when the hopper reaches such point, the operation of the winding drum D can be arrested by any suit-able means. l/Vhen the hopper thus arrives at the posit-ion shown inv Fig. 4, the valve device H is opened by means oi the lever 24' andperrnittcd to swing forwardly into the chute G, whi 'h 'is arranged to regisu ter with opening l1 the mixing receptacle and suitably supported lupon the tilting frame F.. thereby permittingr the hopper-to charge the mixing receptacle.

As one way of connectingl and,disconnecting drum D with and from the engine shaft 4, said drum is supportcdby a rotary shaft 54 (Fig. 5) and this shaft-1s also provided lwith a gear 55 (Fig. 6), which engages a driv! mg )imon 56 secured upon thegengine shaft 4. he gear 55 can be connected with the drum -B by a clutch. device M (Fig. y6), said clutchdevice being splined to slidg along and rotate with shaft 54 and being `constructed with a clutch face or member 57, which can b'e thrown into engagement with` a clutch member 58, it being understood that the gear 55 and clutch member 58 are secured upon a sleeve 5,9 which is loose on the shaft 54, and that the drum D is secured to shaft 54 which extends through the sleeve 59. When it is desired to lower the hoppler, its ,valve gate H can be closed and the opper can be allowed to descend by gravity, the winding drum B being free to revolve, but being controlled however by a hand brake device 58. As a means for tilting the frame F upon which the mixing receptacle is mounted, a substantially bell-crank device 59 is pivoted to one side of the tilting frame as at 60 and provided with a socket 61 for a handle 62. arm ofthe bell-crank and to the opposite arm 63 of the bell-crank is pivoted a longitudinal adjustable link 64, the upper end of said link -belng pivoted to the bell-crank, while its lower end is pivoted to aiixtur'e on the body frame as at 65. By operatin r the handle 62, the frame F can be readily ti ted.

With further reference to the general arrangement oi the device or machine illustrated, the lower or bottom apical portion of the ho )per is provided with a suitable valve controlled discharge opening, while its upper `receiving end portion is practically provided with a lateral or side receiving openlngavhich has an upward exposure when the hopper is in a recumbent position, and that by reason of such laterally exposed receiving opening, the hopper can be charued or loaded asbv durnpingthe contents o a barrel into silch opening or by ,shoveling material therein. But as soon as the charged hopper swings upwardly, the material will not spill out from the side receiving opening and will gravitate toward -the discharge opening. It will also he seen that l provide a portable support or carriage sustaining a rotary mixer having its axis transverse to the length of the carriage and that the mixer arranged as illustrated, tends or serves to counterbalance the inclined track which is supported at its lower end at 1 one sidi` of the carriage and thence. extended rupwardly above the latter, and also, that the mixer servos to (,:ounterbalance the hopper which operates at one side of thc carriage, as hereinhoforo described. Vv'ith reference to the end piece li). its width is proportional lo the desired convenience oi' dumping ninterial into the hopper through its laterally cxposod rec'ering opening 18.

As illustrated in the drawings the opening 18 is on a plane oblique to and intersecting a lino wh'ch may be properly termed the longitudina axis of the hopper. This opening 18 however is also practically lateral to said axis or length oi the hopper, so that when thc hopper is projected outwardly as in Fig. 3

vrsV

The bell socket 61 forms one the hopper.

and thereby in a recumbent or substantially recumbent position, the opening or entrance 18 is presented upwardly for purposes hereiiibeforc described, and wlieli the hopper is irojected upwardly as or substantially as in llig. 4, the opening 18, broadly considered, is lateral to the length or longitudinal axis oi' It will also be scenironi the fore foing descriptionthat the hopper is pivotal y connected with an inclined track structure by means arranged for up and down movement along an inclined way or guide, whereby the axis to which the swinging hopper is tied can bc lowered and raised in alternation.
